This article examines the static area coverage problem by a network of mobile, sensor-equipped agents with imprecise localization. Each agent has uniform radial sensing ability and is governed by first-order kinodynamics. To partition the region of i

With the aim of bridging the gap between high quality reconstruction and mobile robot motion planning, we propose an efficient system that leverages the concept of adaptive-resolution volumetric mapping, which naturally integrates with the hierarchic

In robotic applications, a key requirement for safe and efficient motion planning is the ability to map obstacle-free space in unknown, cluttered 3D environments. However, commodity-grade RGB-D cameras commonly used for sensing fail to register valid

We present an efficient, elastic 3D LiDAR reconstruction framework which can reconstruct up to maximum LiDAR ranges (60 m) at multiple frames per second, thus enabling robot exploration in large-scale environments. Our approach only requires a CPU. W

The selection of the UAV-dispatching stations within the city’s border is amongst the topics addressed in this article. Under the assumption of a concave planar city-area, a constrained minimization problem is formulated, which provides a set of ne

Exploration and collision-free navigation through an unknown environment is a fundamental task for autonomous robots. In this paper, a novel exploration strategy for Micro Aerial Vehicles (MAVs) is presented. The goal of the exploration strategy is t

A control scheme for the coverage of a convex region by a team of mobile aerial agents (MAAs) under positioning uncertainty is presented in this letter. Each MAA is outfitted with a downwards facing camera, the field of view of which differs among ag

Mobile Aerial Agents (MAAs) using localization-sensors suffer from their inherent localization uncertainty. These MAAs are equipped with Pan-Tilt-Zoom (PTZ) cameras and thru their 3D-altitude and camera parameters control survey the area underneath t

The computation problem of the optimal position of collaborating mobile robots equipped with omnidirectional cameras for visual area coverage is the subject of this paper. The planar area has several stationary obstacles resulting in a computationall
